TL;DR: In this paper, a blue shift of the near band-edge photoluminescence (quantum confinement effect) was observed for GaN nanocrystals with a size of ∼2-3 nm, formed in the α-Al2O3 substrate.

Phase Transitions in a Two Component Spin-One Ising Ferromagnetic Superlattice
TL;DR: In this article, the magnetic properties in an infinite superlattice consisting of two different ferromagnets are studied in a spin-one Ising model, and the dependence of the Curie temperature is calculated as a function of the thickness of the two slabs in one period and as the intraand interlayer exchange interactions.
